A username, for the internets. The most rarest of all usernames, too. Only a handful of people use this name. And people whose name is "Nightmare-Box" is most likely a bisexual, teenage, cross-dressing, male weeaboo from North America with nothing to do. A "Nightmare-Box" will use CAPS LOCK when showing affection through the internets. They have a strong obsession for YouTube, 4Chan, and Anime Conventions. They hate MySpace and love cosplaying.
